To all whom it may concern.-

Be it known that LJEROME B. BELL, a citizen of the United States, and a resident of Wilmington, Newcastle county, and State of Delaware, have invented certain'new and useful Improvements in Molds for Linotype- Machines, of which the following is a specification.

This invention relates particularly to improvements in molds and cutters of linotypemachines. In machines of this class as at resent constructed the molds are mounted in rotatable mold-wheels and the inner face or wall of each mold is stationary with re-' spect to the wheel, the outer face being adjustable to produce lines of different thicknesses. On account of the inner or body face of the moldbein non-adjustable the loweredges of t pe of different sizes cast on the machine wil not aline or register. instance, if a slug of brevier t e be alined with a slug of small-pica it willb found that the lower edges of the small-pica faces will be lower than the corresponding edges of the brevier faces. In composition it is desirable that the lower edges of the type of different sizes should aline, and m invention provides means whereby type of ifferent sizes cast on a linotype-machine will aline at their lower edges. I

The invention also comprises a modification of the trimming-knives to adapt them to the modified mold. Y

The invention will be described in connection with the accompanying drawings, in which- Figure 1 is a face view of a portion of a mold-wheel, illustratin m invention. Fig. 2 is an ed e view of aim? -plate and liners removed cm the mold. Fig. 3 is a plan view'of the body-plate shown in Fig. 2. Fig.

. 4 is a plan view of the liners shown in Fig. 2*.

Fig. 5is a rear view of the trimming-knives.

- Fig. 6 is a detail of the adjusting means for the trimming-knives, and Fig. 7 is a plan view of the means for indicating the adjustment.

Referring to Fi s. 1 to 4, inclusive, 1 indicates the mold-w eel, which,.as usual, is in the form of a ear having a toothed periphery. The mo (1 proper comprises a body part 2, a cap 3, an interchangeable liner 4,

and an interchangeable body-plate 5, which ma be a combined body-plate and liner. In inotype-molds as heretofore constructed For the mold-opening 6 has been varied in Width by adjusting the cap, the moldbody 2 being fixed relatively to the mold-wheel. Accordingto my invention I provide for changing the thickness of the mold-openingb adjusting that wall or side of the mol a ainst which is cast the upper face of the typear or slug-that is, the face of the baradjacent to the tops of the type-faces. In applying the invention to a linotype-machine having a rota mold wheel or carrier the inner moldwa l-that is, the one nearer the axis of the mold-wheel-is made adjustable instead of the outer wall, as heretofore. I shall refer hereinafter to the mold-wall against which is .cast the upper face of the type-bar as'the upper wall and to the opposing wall as the lower wall regardless of the particular position in which the mold may beset.- In the accompanying drawings, for instance, the inner mold-wall is the upper wall. I adjust the uppenface of the mold by providing what may be termed body-plates 5 of dif ferent thicknesses, which plates are interchangeable and adapted to be seated upon "to the mold-body. Thus in Fig. 1 is shown a J thin'body-plate havin a'permanent liner 5 combined with a thic short liner 4. This provides a mold-opening for, say, thirty ems of fourteen-point t e, while in Fig. 2 the body-plate 5 is thic er and the liner 4 thinner and longer, thus providing a mold-opening' for, say, thirteen ems of six-point type. It willbe seen that by the use of interchangeable body-plates, to ether with complementary liners, the mo d may be adjusted to bring all type-faces in position on the typebar or sin to effect a lining or registry at the bottomo the t e-faces. Instead of com-' bining the right iner with the body-plate, as shown in Fig. 1,it may be made separate, as shown at 4* in Fig. 2. In my invention the mold-body and the cap always bear a fixedrelation to each other, thedistance between them being equal to the combined thickness too of each body-plate and its complementary liners.

Referring to Figs. 5, 6, and 7, 10 indicates the knife which is adapted to trim the outer face of the slug as'it is ejected fromthe :05

mold-that is, the face which is farther away from the axis of the mold-wheeland 11 is the knife which is ada ted to trim the inner or upper face of the s ug. The knife 11 is made adjustable to ahd from the knife 10 to 'rio correspond with the adjustment of the inner. mold-face by means of the body-plates. For this purpose the knife 11 is provided with inclines 12, which cooperate with corresponding inclines 12 upon a movable wedge-piece 13, which slides between the knife 11 and a track 14. The knife 11 is held in contact withthe wedge-piece 13 by means of. springs 15. The wedge-piece 13 is adjusted vcrti-' cally by means of a screw 16, which, asshown, is squared at its upper end so that it may be turned by a wrench. In order to gage the adjustment of the knife 11, Iprefen ably provide an'indicator. As shown, the indicator comprises a rack 17, which is in mesh with the pinion 18 on the screw 16. The rack is provided with a tooth 19, which is adapted to fit any one of a series of notches in an indicator-plate 20, these notches corresponding to the different thicknesses of s..ugsas, for instance, six-point, sevenoint, &c.' The rack 17 is arranged to roc and slide upon a pin 21, and it is normally held in engagement with the indicator-plate 20 'by means of a spring 22. When it is desired .to

- adjust the mold, the rack is rocked to disengage the tooth 19 from the indicator-plate, and the wedge. 13 is then moved by means of a screw 16, the adjustment being continueduntil the tooth 19 registers with the proper notch in the plate 20.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. In a linotypemachine, the combination With a mold-carrier, of a mold having its wall againstwhich the upper face of the type-bar is cast adjustable, whereby the alinement of the bottom edges of different type-faces may be effected.

2. Ina linotype-machine, the combination with a mold-carrier, of a mold having its wall against which the up er face of the ty e-bar is cast adjustable an its op osing We 1 nonadjustable, whereby the ainement of the 1 bottom edges of different type-faces may be effected.

3. In a linotype-machine, the combination with a mo1d-carrier, of a mold having a fixed body, interchangeable body: lates of differear-.704

type-bar is cast, and a cap forming the opposing wall of the mold.

4. In a linotype-machine, the combination with a mold-carrier, of a mold-body, a series of interchangeable body-plates of different thicknesses, a series of independent liners of different thicknesses complementary to the thicknesses of their respective body-plates,

and a suitable cap forming the outer wall of the mold. I

5. In a linotype-machine, the combination with a mold-carrier, of a mold com rising at mold-body connected with the mol -carrier, a-removable body-plate upon said mold-body and forming the Wall of .the mold against which the upper face of the type-bar is cast, suitable liners, and a cap forming the opposing wall of the mold.

6. In a linotype-machine, the combination with a mold having its wall against which the upper face of-the type-bar is cast adjustable, of trimming-knives, and means for adjusting the trimming-knife which is adapted to shave the upper face of the type-bar.

7. In a linotype-machine, a mold comprising a mold-body and a cap, having a fixed re lation one to the other, interchangeable body-plates with complementary liners capable of being assembled in such manner as to produce a mold-opening having its wall' against which the upner face of the type-bar is cast adjustable and adjustable.

8. In alinotype-machine, the combination with a mold-carrier, of a mold-body upon the carrier, a mold-cap, a series-of body-plates, and a series of complementary liners, the combined thickness of each body-plate and its liners being uniform throughout the series. 9: In alinotype-machine, the combination with a mold-carrier, of a mold-body upon the carrier, a mold-cap, a series'of body-plates,

and a series of com lementary liners, the mold-body and mol -cap being always in fixed relation to each other and to the carrier. 1

In testimony whereof I affix my signature in presence of two witnesses.
